Well here's one of our projects, for the weekend. We were given two bad transformers and the project was to strip them down and empty the oil then taking out the core which someone from Stl was taken. Here's were we had taken the core out and was letting the oil drain. I had my hands all the way in the oil, felt good in the heat and it was NOT PCB. Had to take all the brushings and bolts to get the core out.
